Releasable window guard

Abstract

A protective guard for ground floor windows of a dwelling or other building is disclosed herein having a barred grill or grid network releasably secured to the exterior edge marginal region of a window frame. The releasable securement includes a bolt extending through selected bars of the grill and through the window frame with a pull-out pin installed on the interior end of the bolt. A compressed, helical spring is situated between the frame and the pin for forcibly urging the release mechanism out of engagement with the bolt when the pin is withdrawn. Release of the bolt frees the grill so that the grill may be readily removed to permit passage through the window by persons or objects.

I claim: 
     
       1. A mounting device comprising the combination of: a window frame;   a window guard;   detachable mounting means releasably securing said window guard to said window frame;   each of said mounting means including a headed bolt having a shank passing through said guard and said frame so as to project outwardly from the interior surface of said frame;   pin means removably carried by said bolt shank for retaining said bolt on said frame to support said window guard;   resilient means forcibly and yieldably retaining said pin means engaged with said bolt shank;   a pair of sleeves arranged in telescoping relationship about said bolt shank and each of said sleeves having an enlarged flange exposed adjacent to and bearing against the exterior and interior surfaces respectively of said frame;   said resilient means compressively disposed between the head of said bolt and said window guard;   said bolt being responsive to withdrawal of said pin means to move out of said sleeves in response to expansion of said resilient means;   said bolt shank includes a threaded tip;   a cap threadably engageable with said tip for covering said pin means;   said pin means comprises a straight pin insertably engaged with a registered hole in said bolt shank so as to bear against said sleeve flange opposite to said sleeve flange closest to said window guard; and   said pin covered by said cap preparatory to use for releasing said window guard and disposed in close proximity to the interior of said window frame.
